2.8a Enzymes

1. Enzymes are biological catalysts in metabloical reactions
2. The enzyme makes the reaction occur faster and also under moderate conditions.
3. Metabolic reactions are biological reactions taking place in the cell such as building molecules up or breaking molecules down.
4. To explain how enzymes work, we have the lock and key hypothesis.
5. The red structure represents an enzyme and it also has a particular shape. This conveys that it is a protein as all enzymes are made of protein.
6. The part labelled b is called the active site.
7. This is the part into which the substrate fits.
8. When the substrate does that it forms and activated complex. When it does this, the enzyme is able to weaken the substrate.
9. The substrate is then broken down, split into the product.
10. The enzyme however remains unchanged in this reaction.
